FAQs
What is the primary function of the telescopic feature?
The telescopic feature allows the weep to adapt to varying wall skin thicknesses and provides a way to extend the unit forward during rendering work.
Is the protective cap reusable?
The cap is intended for single-use to protect the unit during installation and should be removed once building works are complete.
Does this weep prevent insects from entering?
Yes, it features an integrated insect-resistant grille to keep pests out while allowing moisture drainage and ventilation.
Can this be used on rendered walls?
Yes, it is specifically designed for use in both standard cavity walls and rendered facades due to its adjustable projection.
What are the physical dimensions of the unit?
The dimensions are 93mm in length, 24mm in height, and 9.5mm in depth, with a 70mm extension capability.
Troubleshooting
Mortar has blocked the weep vent
Ensure the protective cap is kept on during the construction phase. If blocked, carefully clear the mortar using a thin tool, taking care not to damage the internal grille.
Weep is sitting too deep or too far out
Adjust the telescopic section manually before final mortar setting. If already set, you may need to carefully adjust the position if the mortar has not fully cured.

Setup, Compatibility & Care
To install, position the weep within the mortar joint at the required DPC location. Ensure the telescopic segment is set to the correct depth to match your brick or render skin thickness. Keep the protective cap in place throughout the construction phase to prevent mortar ingress. Once construction is complete and the site is cleaned, remove the cap to expose the ventilation grille. No maintenance is required after installation, though a periodic visual inspection should be performed to ensure the grille remains clear of external debris.
